Ok listen up windowlickers, mouthbreathers and nocoiners alike. Lately there’s been a bunch of posts on this forum about stablecoins from people with no understanding of what they are. I’ll try to give a “brief” explanation of what stablecoins are, the different types of stablecoins, the risks and benefits of stablecoins and maybe dive a little into defi and the reasons why stablecoins offer such a high annual return at this time. This is a pretty basic summary, please let me know how wrong I am et al. in the comments below
The traditional financial system
So let’s start with brokerage accounts. I’m assuming everyone here has a brokerage account. Let’s say you want to transfer $1000 from your bank account to your Vanguard account to buy VOO. When you initially deposit this money into your brokerage account, it does not stay in there as cash. You are actually buying a share of a money market mutual fund. Examples of these funds are VMFXX at Vanguard and SPAXX at Fidelity. VMFXX is basically a mutual fund that tries to perpetually maintain it’s value at $1. It holds a combination of assets such as cash, US govt treasury bonds, CDs, etc so that it maintains the share price of VMFXX at $1. The assets that VMFXX holds might change as market conditions change but the value of each chare of VMFXX stays the exact same, $1. So when you deposit $1000 into your Vanguard brokerage account, you’re actually just buying 1000 shares of VMFXX
Here’s a list of what VMFXX holds at this time:

Now there are risks to keeping money in VMFXX. Although Vanguard has been able to maintain the value of VMFXX at $1 for many decades, there is still a possibility that the value could drop below $1 in the future. The money is not backed by FDIC insurance but money market mutual funds like VMFXX are tightly regulated by the SEC and have to follow a certain number of rules in order to protect investors
Why do we need stablecoins?
If we look at the traditional financial system and decentralized finance (Defi from now on), they both exist in parallel with centralized exchanges allowing for the transfer of assets from one system to another
Traditional fiat based financial system ß----à Centralized exchanges ß----à Defi
Centralized exchanges like Coinbase, Gemini, Binance.us, Crypto.com etc will allow you to deposit fiat and convert it into cryptocurrencies which can then be transferred to a Defi application in order to be used in the Defi space. The opposite is also possible where money can be taken from the defi space and converted back into fiat currencies. The system is inefficient, plagued by high fees (charged by centralized exchanges) and limited by the archaic rules of the traditional financial system.
So what happens if you want to move into cash or a cash equivalent asset without leaving the crypto space?
Enter stablecoins
Stablecoins (SC from now on for simplicity’s sake) are cryptocurrencies that are pegged to fiat currencies, most commonly the USD. Think about SCs as the money market mutual funds of the crypto space. They do the same thing as VMFXX. They hold a basket of assets that allow the value of the SC to remain at $1. This allows people to remain in the crypto space while holding USD equivalents, therefore avoiding the high costs of moving between USD and crypto
Examples of different SCs
Before we dive deeper into the assets that are used to back SCs, here are some of the most popular SCs:
-USDC: was created by a partnership between Circle (a defi lending platform) and Coinbase (a centralized exchange). Probably the one SC that most people in the US know about simply because coinbase is the most noob-friendly platform
-GUSD: created by Gemini (a centralized exchange). Gemini was founded in 2014 by the Winklevoss twins (hence the name gemini). Remember them? They got a bunch of money from the Zuck after they successfully sued him for stealing the idea of Facebook from them. They used some of that money to buy BTC early and then founded the exchange in 2014
-BUSD: created by Binance (a centralized exchange). The biggest exchange worldwide, credited with popularizing crypto globally
-USDT: You will often hear people refer to USDT as Tether, one of the earliest SCs and the biggest stablecoin by market cap. There are some specific risks associated with Tether which we can discuss further below
-DAI: a crypto backed SC created by MakerDAO.
-UST: the SC of the Terra/LUNA ecosystem. It is an algorithmically backed SC

Types of SCs
We saw in the link above what assets were used to back VMFXX and maintain it’s peg to the USD. So what assets are used to back SCs?
-Fiat-backed SCs: These are the most popular SCs. They are the exact crypto equivalent to VFMXX. They hold fiat-based assets such as cash, US govt treasuries, CDs, etc in order to maintain their value at $1. Examples of Fiat-backed SCs include USDC, GUSD, BUSD and USDT. For example, when circle/coinbase wants to create 1000 USDCs, they have to acquire $1000 worth of assets to back it up.
-Cryptocurrency-backed SCs: These SCs are backed by cryptocurrencies instead of fiat-based assets. An example of a cryptocurrency-backed SC is DAI. It was initially created in 2017 by MakerDAO (a decentralized autonomous organization, hence the DAO in its name) and was only backed by ETH at that time. It is currently backed by a bag of blue-chip cryptocurrencies including BTC and ETH. Cryptocurrency-backed SCs are generally overcollateralized which means that the value of the cryptocurrencies being held is worth more than 100% of the value of the SC, usually closer to 200%. So let’s say the price of ETH is $1000. If we want to create 500 DAI, we would have to deposit 1 ETH as collateral to back those up. The risk with cryptocurrency-backed SCs is that if the value of the cryptocurrencies that back them drops significantly, they could eventually lose their peg to the USD and could drop in value below $1
-Algorithmically-backed SCs: There are no hard assets backing these SCs, no cash, no treasuries. They are backed by an algorithm that maintains their value at $1. An example of an algorithmic SC is UST. It was created in the Terra/LUNA ecosystem. It’s important to note that there has never been an algorithmically backed SC that has succeeded over a long period of time and most of the attempted ones eventually lost their peg and failed. One of the holy grails of Defi is finding an algorithm that can create an algorithmic SC that remains stable over a long period of time. The current contender is UST. Some of the advantages of algorithmic SCs is that they can provide infinite liquidity to growing markets (like the FED is doing right now) and can separate the value of SCs from fluctuations in the underlying assets (fiat-based assets or crypto-based assets) that are used to back the other 2 categories of SCs described above. They are also void of censorship and cannot be blocked by a central authority.
Advantages of SCs over Fiat
- Reduced cost by not having to move between the crypto space and the traditional financial system back and forth
- Reduced volatility, able to take profits in the crypto space
- Instant settlement, no need to wait for the 48 hour rule present in traditional finance
- Near instant transfer between exchanges and to and from defi apps
